This program puts the output of the cal command on the left, and the output of date and uptime on the right.

var layers = require('text-layers')
var exec = require('child_process').exec

var pending = 3
var commands = [ 'cal', 'date', 'uptime | sed s/,.*//' ]
var output = []

commands.forEach(function (cmd, i) {
  exec(cmd, function (err, stdout) {
    output[i] = stdout
    if (--pending === 0) show()
  })
})

function show () {
  process.stdout.write(layers([
    { text: output[0], x: 0, y: 0 },
    { text: output[1], x: 24, y: 3 },
    { text: output[2], x: 23, y: 4 },
    { text: 'HI', x: 3, y: 3 }
  ]))
}

api

var overlay = require('text-layers')

var output = overlay(layers)

Create a string of output from an array of layers.

Each layer in the layers array can have:

• layer.text - the string to overlay
• layer.x - the x offset, left to right, starting at 0
• layer.y - the y offset, top to bottom, starting at 0

If the layer is a string, its contents are used as the text property with an x and y of 0.
